**  High Performance device driver for the Symbios 53C896 controller.
**
**  Copyright (C) 1998-2000  Gerard Roudier <[e-mail]>
**
**  This driver also supports all the Symbios 53C8XX controller family, 
**  except 53C810 revisions < 16, 53C825 revisions < 16 and all 
**  revisions of 53C815 controllers.
**
**  This driver is based on the Linux port of the FreeBSD ncr driver.

**  The Linux port of the FreeBSD ncr driver has been achieved in 
**  november 1995 by:
**
**          Gerard Roudier              <[e-mail]>
**
**  Being given that this driver originates from the FreeBSD version, and
**  in order to keep synergy on both, any suggested enhancements and corrections
**  received on Linux are automatically a potential candidate for the FreeBSD 
**  version.
**
**  The original driver has been written for 386bsd and FreeBSD by
**          Wolfgang Stanglmeier        <[e-mail]>
**          Stefan Esser                <[e-mail]>
